| DESCRIPTION OF ENHANCEMENTS |
This patch is one in a series of patches to support the VA's transition
This patch updates several places where IPv4 address formats were
hard-coded in routines, and have now been replaced with calls to
IPv4/IPv6 Application Programmer Interfaces (APIs) to support the VA's
transition to IPv6. Several changes have also been made in algorithms
that will improve the efficiency of IP address handling.
No current functionality has been changed. IPv6 functionality for future
support cannot be completely tested until additional changes are made in
VistA, and a test environment is established to replicate the planned VA
network architecture.
from IPv4 to IPv6. IPv6 is a protocol designed to handle the growth rate
of the Internet and to cope with the demanding requirements of services,
mobility, and end-to-end security. A Federal Chief Information Office
(CIO) memo "Transition to IPv6" released in September of 2010 requires
agencies to continue their IPv6 transition efforts and has established
specific milestones associated with enabling an IPv6 operational
capability by the end of FY2014.
